Council For The Indian School Certificate Examinations [Cisce] — Complaining about wrong question asked in ISC class 12 computer science examination

Address:

Delhi India

Dear sir/madam,
I would like to bring to your attention that yesterday ISC computer science exam was held in which one question was wrong and for the same the answer provided is also wrong .
I am talking about Q9 stating "The combinational circuit capable of adding two 3 bit number is"
The official answer key provided tell us that option B "Full adders" is the correct answer but according to my search I come up with following statements :-
1. If the question is asked to add 2 number answer would be half adders.
2. If the question is asked to add two 3 bit numbers then also answer is not Full adders but the answer is 2 Full adders and 1 half adders.
3. The answer mentioned in above point 2 is not in the question paper . Moreover the addition of two 3 bit numbers is not in the syllabus of ISC class 12.
4. But for the benefit of doubt if the question asked was to add three 2 bit numbers then the answer will be full adders but clearly we can see question was not so asked.
If the question was a misprint and a mistake then why should students should suffer with mistakes of council.
Thanks for reading my doubt. I hope you will take a valid action against this so that students do not have to suffer.
